ORR policy (42 pages, PDF) on the approval of long-term track access options to support infrastructure investment projects. The document includes use-it-or-lose-it rules and a formula for the compensation to be paid for compulsory cancellation of the option. A conclusions document (47 pages, PDF) explains the policy and states that “the implications of [use it or lose it] for the rebate mechanism will need to be given further consideration”. These documents are released ahead of the closed industry hearing on the Crossrail track access option on 1 February 2008.
